No they are in the Small Breed group.
Jack Russell terrier and Welsh corgi.
The Jack Russell is a smaller version of a Fox terrrier. A Fox terrier is derived from a wolf. I belive they just kept breeding small-legged Fox terriers until they got the Jack Russell terrier.
I've just got a jack russell shih tzu cross puppy. He's called a jack tzu.
No, they aren't. Both coat types shed hair. This is not a recommended breed for people who are allergic to dogs. However, some Jack Russell mix breeds, such as Jack Russell/Poodle mixes, are hypoallergenic.
All dogs are susceptible, particularly smaller breeds.
Some mixed breeds of dogs include the jack-chi, which is a Jack Russell terrier Chihuahua mix. Another mixed breed is the Goldador which is a Golden retriever and Labrador mix.

the bigest player in the world ----------------------------------------------------------------------------------------- http://www.akc.org/breeds/parson_russell_terrier/index.cfm The Parson Russell terrier is a name change; it was formally the Jack Russell terrier.
New answer. The Jack Russell's full bred name is the Jack Russell Terrier. In his book The Intelligence of Dogs, probably the best book on the subject, Stanley Coren describes intelligence tests he uses to find a dog's intelligence and he rates many breeds. His list of 79 breeds shows no terriers until #27 and most of the terriers start to show up on the list between #47 and #79. This means that generally speaking most terrier breeds are in the lower half of the list in intelligence. Jack Russell Terriers, which are noted for their intelligence, were not ranked because they were not recognized by the AKC until 2013. Coren did not include breeds recognized elsewhere but not in North America.
Rat terriers and Fox terriers are their own breed of dog. They all come from the same lines, going centuries back. But now due to breeding, these different breeds of dog have different characteristics although they may look alike they are in fact not all Jack Russell's.
Unless the Jack Russell was bred with a Golden Retriever then no, it is not physically possible. If your Jack Russell has given birth to Golden Retriever puppies, then clearly, your dogs magic. The only solution.
